In this paper, we give some sufficient conditions for the Dominguez–Lorenzo condition in terms of the James type constant $$J_{X,t}(\tau )$$ , the coefficient of weak orthogonality $$\mu (X)$$ and the Dominguez Benavides coefficient R(1, X), which imply the existence of fixed points for multivalued nonexpansive mappings. Our results extend some well known results in the recent literature.

多值非扩展映射的 James 类型常量和不动点

在本文中,我们根据 James 类型常数 $$J_{X,t}(\tau )$$ ,弱正交系数 $$\mu (X)$ 给出了 Dominguez-Lorenzo 条件的一些充分条件$ 和 Dominguez Benavides 系数 R(1, X),这意味着多值非扩展映射存在不动点。我们的结果扩展了最近文献中一些众所周知的结果。
